Clevudine is a pyrimidine analogue with potent and sustained antiviral activity against HBV. The present study evaluated the safety and efficacy of 30 mg clevudine once daily for 24 weeks and assessed the durable antiviral response for 24 weeks after cessation of dosing. A total of 243 hepatitis B e antigen (HBeAg)-positive chronic hepatitis B patients were randomized (3:1) to receive clevudine 30 mg once daily (n ‫؍‬ 182) or placebo (n ‫؍‬ 61) for 24 weeks. Patients were followed for a further 24 weeks off therapy. Median serum HBV DNA reductions from baseline at week 24 were 5.10 and 0.27 log 10 copies/mL in the clevudine and placebo groups, respectively (P < 0.0001). Viral suppression in the clevudine group was sustained off therapy, with 3.73 log 10 reduction at week 34 and 2.02 log 10 reduction at week 48. At week 24, 59.0% of patients in the clevudine group had undetectable serum HBV DNA levels by Amplicor PCR assay (less than 300 copies/mL). The proportion of patients who achieved normalization of alanine aminotransferase (ALT) levels was 68.2% in the clevudine group and 17.5% in the placebo group at week 24 (P < 0.0001). ALT normalization in the clevudine group was well maintained during post-treatment follow-up period. The incidence of adverse events (AEs) was similar between the clevudine group and the placebo group. No resistance to clevudine was detected with 24 weeks of administration of drug. Conclusion: A 24-week clevudine therapy was well tolerated and showed potent and sustained antiviral effect without evidence of viral resistance during treatment period in HBeAg-positive chronic hepatitis B.

The mean age of patients with gastric cancer has increased during the past 20 years. The proportion of early gastric cancer and overall survival have gradually increased, especially in patients aged over 40 years.

A 24-week clevudine therapy was well-tolerated and showed potent and sustained antiviral effect without evidence of viral resistance in e-CHB patients. However, treatment for longer than 24 weeks would be needed to achieve durable remission.

These data propose elevated plasma OPN levels as a potential biomarker for HCC.

Background/AimsPortal-vein thrombosis (PVT) develops in 10-25% of cirrhotic patients and may aggravate portal hypertension. There are few data regarding the effects of anticoagulation on nonmalignant PVT in liver cirrhosis. The aim of this study was to elucidate the safety, efficacy, and predictors of response to anticoagulation therapy in cirrhotic patients.MethodsPatients with liver cirrhosis and nonmalignant PVT were identified by a hospital electronic medical record system (called BESTCARE). Patients with malignant PVT, Budd-Chiari syndrome, underlying primary hematologic disorders, or preexisting extrahepatic thrombosis were excluded from the analysis. Patients were divided into two groups (treatment and nontreatment), and propensity score matching analysis was performed to identify control patients. The sizes of the thrombus and spleen were evaluated using multidetector computed tomography.ResultsTwenty-eight patients were enrolled in this study between 2003 and 2014: 14 patients who received warfarin for nonmalignant PVT and 14 patients who received no anticoagulation. After 112 days of treatment, 11 patients exhibited significantly higher response rates (complete in 6 and partial in 5) compared to the control patients, with decreases in thrombus size of >30%. Compared to nonresponders, the 11 responders were older, and had a thinner spleen and fewer episodes of previous endoscopic variceal ligations, whereas pretreatment liver function and changes in prothrombin time after anticoagulation did not differ significantly between the two groups. Two patients died after warfarin therapy, but the causes of death were not related to anticoagulation.ConclusionsWarfarin can be safely administered to cirrhotic patients with nonmalignant PVT. The presence of preexisting portal hypertension is a predictor of nonresponse to anticoagulation.
